My second BM Element, after the White Wheel Lift. It can perform the functions of a path selector, a dropper, and a pair of maracas - all at the same time!
Step 1: Parts List
The pieces you'll need for the 2x2 dropper are -
2 x Yellow Rods
1 x Orange Connector
2 x Large Wheel
2 x Hubcap Wheel (Large) w/ Tyre
Step 2: Building
Just assemble it as shown in the pictures, it's pretty simple.
Step 3: Done!
If you've made it, and are happy with its performance, post an IMI for support! I'll add those pictures to this step.
